THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL
STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT
WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT
SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR
LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required
to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not
installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to
comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital
devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television
communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its
peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits
controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Product Overview
The Catalyst 3560 switch—also referred to as the switch—is an Ethernet switch to which you can
connect devices like workstations, Cisco Wireless Access Points, Cisco IP Phones, and other network
devices such as servers, routers, and other switches. This chapter provides a functional overview of the
Catalyst 3560 switch. These topics are included:
• Setting Up the Switch, page 1-1
• Features, page 1-1
• Front Panel Description, page 1-3
• Rear Panel Description, page 1-15
• Management Options, page 1-20

Features
See the Catalyst 3560 Switch Getting Started Guide for instructions on how to use Express Setup to
initially configure your Catalyst switch. The getting started guide provides switch management options,
basic rack-mounting procedures, port and module connections, power connection procedures, and
troubleshooting help.
For instructions on setting up your switch using the command-line interface (CLI), see Appendix D,
“Configuring the Switch with the CLI-Based Setup Program.”
The 24- and 48-port Catalyst 3560 switches can be deployed as backbone switches, aggregating
10BASE-T and 100BASE-TX Ethernet traffic from other network devices. The Catalyst 3560-8PC and
the Catalyst 3560-12PC-S compact switches provide the same Power over Ethernet (PoE) connectivity
and can be deployed outside the traditional wiring closet environment, such as in office workspaces and
classrooms. The switches are hot-swappable. See the switch software configuration guide for examples
of how you might deploy the switch.
For power redundancy, all but the Catalyst 3560 8- and 12-port switches include connections for an
optional Cisco RPS 2300 or Cisco RPS 675 that operates on AC power and supplies backup DC power
to the switches.

Chapter 1 Product Overview
The 10/100/1000 ports on the Catalyst 3560G-48TS switch are grouped in pairs. The first member of the
pair (port 1) is above the second member (port 2) on the left, as shown in Figure 1-10. Port 3 is above
port 4, and so on. The SFP module slots are numbered 49 to 52.
Figure 1-10 Catalyst 3560G-48TS Switch Front Panel
1 10/100/1000 ports 2 SFP module slots
10/100 and 10/100/1000 Ports
• You can set the 10/100 ports to operate in any combination of half duplex, full duplex, 10 Mb/s, or
100 Mb/s. You can set the 10/100/1000 ports to operate at 10 or 100 Mb/s in half or full duplex or
at 1000 Mb/s in full duplex.
• You can set both the 10/100 and the 10/100/1000 ports for speed and duplex autonegotiation, in
compliance with IEEE 802.3ab. (The default setting is autonegotiate.)
• You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet interfaces if the
speed is set to 10 or 100 Mb/s. You cannot configure half-duplex mode on Gigabit Ethernet
interfaces if the interface speed is 1000 Mb/s.
• When set for autonegotiation, the port senses the speed and duplex settings of the attached device
and advertises its own capabilities. If the connected device also supports autonegotiation, the switch
port negotiates the best connection (the fastest line speed that both devices support and full-duplex
transmission if the attached device supports it) and configures itself accordingly. In all cases, the
attached device must be within 328 feet (100 meters).
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security.
Statement 1072
• 100BASE-TX and 1000BASE-T traffic requires Category 5 cable. 10BASE-T traffic can use
Category 3 or Category 4 cables.

Chapter 1 Product Overview
PoE Ports
Front Panel Description
• When you connect the switch to workstations, servers, routers, and Cisco IP Phones, be sure that the
cable is a straight-through cable. When you connect the switch to switches or hubs, use a crossover
cable. When using a straight-through or crossover cable for 1000BASE-T connections, be sure to
use a twisted four-pair, Category 5 cable for proper operation. Pinouts for the cables are described
in Appendix B, “Connector and Cable Specifications.”
• You can use the mdix auto interface configuration command to enable the automatic
medium-dependent interface crossover (auto-MDIX) feature. When the feature is enabled, the
switch detects the required cable type for copper Ethernet connections and configures the interfaces
accordingly. Therefore, you can use either a crossover or a straight-through cable for connections
to a copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the
type of device on the other end of the connection.
The auto-MDIX feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or
later. For releases between Cisco IOS Release 12.1(14)EA1 and 12.2(18)SE, the auto-MDIX feature
is disabled by default. For configuration information for this feature, see the switch software
configuration guide or the switch command reference.
• The10/100 and 10/100/1000 PoE ports on the switch provide PoE support for devices compliant
with IEEE 802.3af and Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet
Access Points.
• Each of the Catalyst 3560-8PC, 3560-12PC-S, 3560-24PS, and 3560V2-24PS switch 10/100 ports
or the Catalyst 3560G-24PS switch 10/100/1000 ports deliver up to 15.4 W of PoE.
On the Catalyst 3560-48PS, 3560G-48PS, and 3560V2-48PS switches, any 24 of the 48 10/100 or
10/100/1000 ports delivers 15.4 W of PoE, or any combination of the ports delivers an average of
7.7 W of PoE at the same time, up to a maximum power output of 370 W.
The Catalyst 3560-12PC-S switch delivers a maximum power output of approximately 125 W total
PoE power.
• On a per-port basis, you can control whether or not a PoE port automatically provides power when
an IP phone or an access point is connected. The device manager, Network Assistant, and the CLI
provide PoE settings for each 10/100 or 10/100/1000 PoE port:
–
Auto: When you select the Auto setting, the port provides power only if a valid powered device,
such as an IEEE 802.3af-compliant powered device, a Cisco prestandard IP phone, or a Cisco
prestandard Cisco access point, is connected. The Auto setting is the default.
–
Never: When you select the Never setting, the port does not provide power even if a Cisco
IP phone or an access point is connected.
• You can connect a Cisco IP Phone or Cisco Aironet Access Point to a Catalyst 3560 PoE switch
10/100 or 10/100/1000 port and to an AC power source for redundant power. The powered device
might change to the AC power source as its primary power source when connected to it. In that case,
the PoE port becomes the backup power source for the powered device.
OL-6337-07
If the primary source fails, the second power source becomes the primary power source to the
powered device. During the power transfer, an IP phone might reboot or reestablish link with the
switch.
For information about configuring and monitoring PoE ports, see the switch software
configuration guide. For information about Cisco IP Phones and Cisco Aironet Access Points, see the
documentation that came with your IP phone or access point.
Catalyst 3560 Switch Hardware Installation Guide
1-9
Front Panel Description
126809
Many legacy powered devices, including older Cisco IP phones and access points that do not fully
support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.
SFP Module Slots
See the release notes for the latest list of supported SFP modules.
SFP Modules
The switch uses Gigabit Ethernet SFP modules to establish fiber-optic and 1000BASE-T connections.
These transceiver modules are field-replaceable, providing uplink interfaces when inserted in an
SFP module slot. Use fiber-optic cables with LC or MT-RJ connectors to connect to a fiber-optic
SFP module. Use a Category 5 cable with RJ-45 connectors to connect to a copper SFP module.
For more information about SFP modules, see your SFP module documentation or the release note for
your switch software.
SFP Module Patch Cable
Chapter 1 Product Overview
The switch supports the SFP module patch cable (CAB-SFP-50CM=), a 0.5 meter, copper, passive cable
with SFP module connectors at each end (see Figure 1-11).
Figure 1-11 SFP Module Patch Cable
The SFP module patch cable can connect only two Catalyst 3560 switches. To connect a
Catalyst 3560 switch to other Catalyst series switches, you must use the SFP modules specified in the
“SFP Module Cable Specifications” section on page B-4.
See “Inserting and Removing the SFP Module Patch Cable” section on page 2-18 for more information
about using the SFP module patch cable.
Dual-Purpose Port
You can configure a dual-purpose port as either a 10/100/1000 port or as an SFP module port. Each port
is considered as a single interface with dual front ends—an RJ-45 connector and an SFP module
connector. The dual front ends are not redundant interfaces. The switch activates only one connector of
the pair at a time.
By default, the switch dynamically selects the interface type that first links up. However, you can use
the media-type interface configuration command to select the RJ-45 connector or the SFP module
connector. For information about configuring speed and duplex settings for a dual-purpose uplink, see
the software configuration guide.
Each uplink port has two LEDs. One shows the status of the RJ-45 port, and one shows the status of the
SFP module port. The port LED is on for the active connector.

being accidentally removed. To order a cable guard (CBLGRD-C3560-12PC or CBLGRD-C3560-8PC),
contact your Cisco representative. The cable guard serves a different purpose than the cable guide (see
“Attaching the Cable Guide” section on page 2-11).

Internal Power Supply
An internal power supply powers the switch. The internal power supply is an autoranging unit that
supports input voltages between 100 and 240 VAC. Use the supplied AC power cord to connect the AC
power connector to an AC power outlet.
DC Power Connector
The Catalyst 3560V2-24TS-SD has an internal DC-power converter. It has dual feeds (A and B) that are
diode-OR-ed into a single power block. For installation instructions, see Appendix C, “Connecting to
DC Power.”
Caution You must connect the Catalyst 3560V2-24TS-SD switch only to a DC-input power source that has an
input supply voltage from –36 to –72 VDC. If the supply voltage is not in this range, the switch might
not operate properly or might be damaged.

Cisco RPS
Note When an RPS is connected to the Catalyst 3560V2-24TS-SD switch, the switch is not Network
Note The Catalyst 3560-8PC and Catalyst 3560-12PC-S switches do not have an RPS connector.
Rear Panel Description
Depending on the switch model, you can connect the switch to either of these Cisco redundant power
systems (RPS) to provide backup power if the switch power supply fails:
• “Cisco RPS 2300” section on page 1-19
• “Cisco RPS 675” section on page 1-19
Connect the switch and the Cisco RPS to the same AC power source. Use the RPS connector cable
supplied with the RPS to connect the RPS to the switch.
Equipment Building Systems (NEBS) compliant.
For complete information about the Cisco RPS products, including compatibility matrixes listing the
supported RPS for each Catalyst 3560 switch, see the RPS documents on Cisco.com:

The Cisco RPS 2300 is a redundant power system that supports six network switches and provides power
to one or two failed switches at a time. It automatically senses when the internal power supply of a
connected switch fails and provides power to the failed switch, preventing loss of network traffic.
The Cisco RPS 2300 has two output levels: -52 V and 12 V. The maximum output power depends on the
installed power-supply modules.
The Cisco 675 RPS is a redundant power system that supports six network devices and provides power
to one failed switch at a time. It automatically senses when the internal power supply of a connected
switch fails and provides power to the failed switch, preventing loss of network traffic.
The Cisco RPS 675 has two output levels: –48 V and 12 V. The maximum output power is 675 W.
You can connect the switch to a PC by means of the console port and the supplied RJ-45-to-DB-9 female
cable. If you want to connect the switch console port to a terminal, you need to provide an
RJ-45-to-DB-25 female DTE adapter. You can order a kit (part number ACS-DSBUASYN=) containing
that adapter from Cisco. For console port and adapter pinout information, see the “Connector and Cable
Specifications” section on page B-1.
